Whenever it gets to minus 30C or colder, I take the day off. So many things can happen when it gets to those temperatures. I've had no starts, frozen fuel, gelled coolant... etc. Sometimes it's better to write the day off as opposed to doing equipment damage. Just because it starts, doesn't mean you are going to have a "trouble free" day.
Pretty incredible that those various oils would have about the same viscosity at engine operating temperatures! Ah, the wonders of viscosity index improvers...
Ow and it's not all good to run 0w20 and 0w30. It's all a matter of cons and pros. Best if we had summer and winter oils. But hey we do stupid stuff like feed exause gases into or engines. We do care about them don't we?
@@brandon9715 yes, but you’ll be paying over double the price for a 0w30 to perform and last as long as a 10w30. Total waste of money if you live in a warmer climate.
@@brandon9715 The downside isn't that 0 weight oil can be too thin at startup, the potential downside is that a lot of the time 0 weight oils also have worse high temperature performance than 5, 10, or 15 weight oils since they tend to be made out of thinner base oils with more viscosity modifiers. That's not to say that 0 weight oils can't perform well in the heat as many obviously do, but if you look at the specs for the same product line in different ratings, you will often see lower flash points, lower HTHS viscosity, and higher NOACK volatility as the cold viscosity rating drops. Look at data sheets from Amsoil, Mobil 1, Redline, etc and see for yourself. Again, I'm not saying a 0 weight oil won't be adequate for summer use, just that there can be less obvious downsides.
What Car is rolled in at 4:42 ? The engine looks very much like a Ford 2,0 OHC from the eighties in Europe (Sierra, Taunus and Granada), but I have never seen one in aluminum, with screwed cam Towers and roller cam.
i have seen several engines blow up that were using 5w-30 in the summer and others that made awful noise when using that cheap oil but none that were using something heavier like straight 30 or 40
what if i live in a climate where the coldest it ever gets is 25 deg celsius.....but the hottest can be 40 deg celsius? is the ''w'' rating of any use? or can i jus use straight 15w40 or 20w50
25 degrees C is 77 degrees F. At those temps, the cold viscosity rating is irrelevant. Look at the owners manual. As long as XW40 or XW50 is listed as acceptable for those temps, you can use it no problem.

@@V8Lenny really? Have the gap clearance in modern engine was improved since in the past? i mean since world war II the gap clearance is 30 micron which is very small than hair thickness *Sorry 10 micron.
The video clearly is clearly discussing the lubrication of engines, not wind tunnels. If air is such a great lubricant, drain the oil from your engine and go for a drive then let us know how that worked out.
There is a very good Engineering Explained Video talking about how the 2 numbers of Multi weight oils viscosity index get closer to each other as the oil wears out from use.
No engine ever complains about oil being "too thin" at startup, it's much thicker than at operating temp anyway. If it doesn't go below -10 °C often, you'd be just alright with 5w tho, it is a bit cheaper at least. There is no point going with 10w or higher, specially since most of these oils are not very good quality.
You aren't very good with geography eh? Canada is HUGE, and many parts of the northern US along our border gets the same weather. Fortunately carburetors are nearly extinct, so hard starts or no-starts are rare, but we NEED thin oil in the winter here 🇨🇦
It hits -40F sometimes in Montana and Wyoming, right here in the northern US! I'm sure Minnesota and the Dakotas see temps that low too, as you get closer to the oceans, left and right from the center of the continent it doesn't get as cold, but still definitely below zero in the winter for places like Washington, Idaho, New York, and Maine. You must be a very sheltered individual to not know that 🤔
Well, this video wasn't rigged at all. A synthetic blend 0W30 vs conventional 15W40 and 10W30 at -35 degrees? No, not rigged at all. And if you have a car or truck at that temp, you had better have it plugged in overnight. Common friggin sense.
I know it's an old comment, but nothing is rigged, that's just what happens at those temps. If your vechicle hardly experiences below zero temperatures you'd be alright with 15w I guess, but there is still no point in using a "thicker" oil, apart from money saving, on the other hand most 0w/5wXX oils are much better overall quality than 10/15wXX so you could go longer before changing, negating much of the money difference while still flowing much better, even at not very cold startup. If it does go to over -30 often, you really need 0w (or at least 5w) oil unless you preheat the engine with an electric heater, but it's not always possible and is it really worth the trouble?
@@piciu256 If you ignore HTHS viscosity, NOACK volatility, and the possibility of viscosity modifiers shearing and degrading over time, you are correct that there is no reason to use "thicker oils" than 0W or 5W.

Thanks for uploading this. I remember watching this years ago in automotive mechanics school. Very good information.
Me in Florida where it stays 94°F in winter:
“Damn, I better switch to 0W-30”
I lived 30 miles south of the Canadian border in NY and ran 5W-30 year round in my vehicles with no issues.
Same here. I used dinosaur juice for a really long time and even 10w30 and never had such an issue.
@@paulstandaert5709 Nice man. I used 10W-30 in the summer even though it doesn't get that hot outside.
0w20 and 0w30 should be way more common and standard equipment in any place that gets past -20 centigrade
Or common humans shoud have common standard brains... Or atleast have a motor heater going for 3h-4h before starting there vehicle. (helps allot)

Dodge Shadow or Plymouth Sundance. I think that it's a Dodge Shadow.
Modern oils are now so much better
nice video thanks fot it
That Dodge Shadow :D
I have one 2.5 lts turbo. Y currently use it and i plan restore the car completly. Y love this vehicle so much.
it makes me appreciate that i live somewhere where max cold is -2
why dont you fix a heater in oil pan ??? For pre heating.
That last one looks like a 3 coffee morning after a Taco Bell dinner.💩

Idiot!
Should I have said the USSR?
David Z You shouldn't think badly about Russians at all. Understand? ;)))
he said "us Russians" as in he is Russian I would assume, still a bad joke regardless
Minus 35 wouldn’t car turn on except block heater help. Gas will be frozen easily

@@blackmambaaa41 how do you know what i have seen? you are the BSer
What's the best oil to use when out side temperature low is 40 F high is 80 F
consult your owners manual
What engine? Tuned? Prolly either 0w-30, 5w-30, 0w-40, or 5w-40.
Where is part 2?
My favourite part was the part where there is a part of a non activated part
… which part was that?
good video
6:00 so thats where microsoft got that windows 10 sound from
exactly what i was thinking lol
Is this why block heaters exist?
what if i live in a climate where the coldest it ever gets is 25 deg celsius.....but the hottest can be 40 deg celsius? is the ''w'' rating of any use? or can i jus use straight 15w40 or 20w50
25 degrees C is 77 degrees F. At those temps, the cold viscosity rating is irrelevant. Look at the owners manual. As long as XW40 or XW50 is listed as acceptable for those temps, you can use it no problem.
you should never crank for more than 30 seconds at a time? that seems a little long
It's liable to be REALLY flooded out after cranking for that long!
Nice video,thanks.
i live ina a coastal city so...in fact .ive never seen snow ever,,,and may be i wont
0W oils and block heaters mean I have no issues started in the coldest of temperatures.

I live in 9°c - 39°c i use 15w40 is it right?
sounds good to me, however you can’t argue with what your vehicle manual says
That would be fine to use for those temperatures.
You can use 20w50, its my preferred oil at these and hotter temps
Depends what your bearing clearances are. 40 is too thick for most modern engines.

sorry uploaded a 2nd version look under my videos should be in its entirety
35 *what* below zero ?
cams are soo worn
not sure were the text came from sorry if you have any idea how to remove let me knowthanks
-35 is not common.. I would love to see the same on -20 I bet i would be a huge difference
Depends where you are. It can be -35 Celsius easily in central Saskatchewan if you go north, -40 is not unreasonable.

Air is most definitely a lubricant. It has been used to lubricate windtunnel belts for decades.

How much, if any, does cold viscosity rating of the oil degrade with use?
There is a very good Engineering Explained Video talking about how the 2 numbers of Multi weight oils viscosity index get closer to each other as the oil wears out from use.
It all depends on how the engine is used. But under "normal" operating conditions... the oil gets thicker.
@@mareksumguy1887 multi viscosity oils gets thinner because VI improvers breaks down.
@@V8Lenny it’s not that simple. It depends on the quality of the oil.
I can tell you that all this oil is junk compared to oil today same principles.
I'm usin only mineral oil or semi synthetic. 20w50 or 15w40 for summer and 5w40 or 10w40 for winter.
pour an little sea foam in it
Non activated version 😆
Alaska and Siberia is just a small part of the world with not much cars around.. why do they develop so many 0W oils for that usage ?

There is no point going with 10w or higher, specially since most of these oils are not very good quality.
Also I'm pretty sure having 0w oil is better whenever it's pretty cold(like below 0c), so it will won't hurt
